Import Di Double Flange Tape — Buy in Bulk from Supplier in China

The Di Double Flange Tape from Jilin Senfeng Pipe Co., Ltd. is a ductile iron component designed for sealing flanged joints in pipeline systems. It conforms to ISO2531, BS EN545, BS EN598, AWWA C219, AWWA C110, and ASME B16.42 standards, with a nominal pressure rating of PN10. The tape features dual flanges with precise alignment grooves to ensure leak-tight performance under dynamic pressure conditions. Dimensions are standardized for compatibility with DN50 to DN1200 pipe systems, and the material composition follows EN GJS-400-15 ductile iron specifications.

The tape is manufactured from nodular graphite iron with a minimum tensile strength of 400 MPa and elongation of at least 15%, meeting standard requirements for cast iron fittings. Surface finish is typically sandblasted and coated with bituminous paint for corrosion resistance, though epoxy or fusion-bonded epoxy coatings are available on request. This grade of ductile iron offers superior impact resistance compared to gray iron, making it suitable for underground installations and seismic zones. The material is free from excessive porosity or inclusions, as verified by ultrasonic testing in production batches.

This component is commonly purchased by municipal water utilities, industrial plant contractors, and pipeline construction firms in Asia, the Middle East, and Eastern Europe. Buyers typically order in quantities of 50 to 500 units per shipment, packaged in wooden crates with anti-rust paper lining. Trade terms are commonly FOB Dalian or CIF port of destination, with lead times ranging from 25 to 40 days after deposit. Custom markings for project codes or logos are supported upon request.

Jilin Senfeng Pipe Co., Ltd. operates from Panshi, Jilin Province, China, with a registered address at B-1, Jiancaijiayuan, Fukang Road. The company is classified as a harbor-tier supplier, indicating verified production capacity and export documentation compliance. Its profile shows no public claims regarding annual output, workforce size, or client names. It is listed as a manufacturer of ductile iron fittings, not a trading company, based on its facility location and product focus.

The supplier has no publicly available certifications such as ISO 9001 or CE marked in the listing, nor any stated years in operation. Response metrics show zero response rate and zero average response hours, suggesting limited buyer communication capability. Buyers should treat this as a production facility with documented export experience but unverified customer service responsiveness. No claims about past projects, certifications, or international clients are supported by the source data.
